Our new-to-us 94 HR pusher doesn't warm up enough to really heat the driver's area up front. We were told the heater core had just been replaced, but the air we get is barely warm. Our engine water temp gauge just comes up above the cold mark. Any suggestions on what to do while the weather is still cool? Thanks, Harvey

gordan23 is correct and i would also add to have them pressurize the system as having put in the new core could have inducted air into the system and could be showing itself as a blockage to full coolant flow.just a suggestionand hope it helps. terry

Thanks for these ideas. I'll probably be doing the work myself. By presurize the system, does that mean using one of the radiator caps that you can attach to a pump, as if you were testing for a leak? Thanks, HarveyP

sorry for not responding sooner, but yes it is the style cap you mention. be careful not to over do it as that will lead to a new set of problems. just raise the pressure slowly. the caps i have seen have very good instructions and have been part of a kit. if you need to, feel free to pm me with any questions and hopefully i can help somewhat faster this next time. good luck, terry
